  • In the heart of Missouri, Capital Quarries keeps the beat with its 944K hybrid wheel loaders

    Nestled between neighborhoods and freshly built super stores not five minutes from the State Capitol building in Jefferson City, Missouri, sits an unexpected pocket of industry. Other than the crisp limestone bluffs acting as a backdrop, this quarry is nearly undetectable from the surrounding thoroughfares, although its products have played a significant role in the infrastructure that has sprung up around it. The site is home to Capital Quarries Company and just one of the organization�s 16 active mines.
